The general expectation of patients who come in for orthodontic treatment is not only to obtain a good occlusal relationship but also to achieve a certain level of esthetic improvement. Therefore, contemporary orthodontic treatment has to take facial structures and varieties into consideration. Consequently this experiment was based on previous research on most preferable profiles, and we once again, conducted survey the preference of people concerning the non-preferable profiles. The followings are the results of this survey. 1. The least preferable profiles are the ones with lips deficiencies (lip retraction and protrusion). 2. Among assorted types of lip deficiency, protruding lips are the least favored. 3. This was the choice of all those tested among all groups of profiles. The results of survey are in accordance with those of previous survey on ideal profiles.
